如何使用Pandas将日期范围划分为两个月一组？

import pandas as pd
import numpy as np

start_date = pd.to_datetime('2022-01-01')
end_date = pd.to_datetime('2023-12-31')
date_range = pd.date_range(start=start_date, end=end_date, freq='MS')

groups = np.array_split(date_range, len(date_range) // 2)

import pandas as pd
import numpy as np

start_date = pd.to_datetime('2022-01-01')
end_date = pd.to_datetime('2023-12-31')
date_range = pd.date_range(start=start_date, end=end_date, freq='MS')

groups = np.array_split(date_range, len(date_range) // 2)

for i, group in enumerate(groups):
    print(f'Group {i+1}:')
    print(group)
    print()
